Jihoon Kim, M.S., Principal Statistician, UCSD Health Dept. of Biomedical Informatics.  "Privacy-Protecting, Reliable Response Data Discovery Using COVID-19 Patient Observations."

Abstract:  We developed a distributed, federated network of 12 health systems that harmonized their EHRs and submitted aggregate answers to consortia questions posted at https://covid19questions.org/. Our consortium developed processes and implemented distributed algorithms to produce answers to a variety of questions. We were able to generate counts, descriptive statistics, and build a multivariate, iterative regression model without centralizing individual-level data. Our public web site contains answers to various clinical questions, a web form for users to ask questions in natural language, and a list of items that are currently pending responses. We demonstrated that it is possible to answer questions about COVID-19 using EHR data from systems that have different policies and must follow various regulations, without moving data out of their health systems. We present an alternative or complement to centralized COVID-19 registries of EHR data. We can use multivariate distributed logistic regression on observations recorded in the process of care to generate results without transferring individual-level data outside the health systems.

Robert A. Greenes, M.D., Ph.D., Emeritus Professor and Ira A. Fulton Chair in Biomedical Informatics
Arizona State University and Mayo Clinic. "Knowledge-Enhanced Health IT: Clinical Decision Support & Beyond."

Abstract: The prospect of using computers to enhance healthcare with knowledge captured academic and professional interest from its earliest days, more than six decades ago, when computer-aided diagnosis was a hot topic. Clinical decision support (CDS) – in the form of targeted information retrieval, alerts, reminders, order sets, templates for data entry and reporting, and visualizations that portray patient status or trends at a glance – have been an important part of most operational clinical systems.

However, the challenges of implementing knowledge artifacts so that they work well in different settings and with different workflows, are sufficiently patient-specific, and are able to be maintained and updated regularly have been huge. Also the negative aspects of poor use of CDS have resulted in user dissatisfaction, alert fatigue, and other complaints, and have been blamed for contributing to physician burnout. The penetration of CDS, as a result, has been far less than desirable.

Many disruptive changes in our current environment raise the possibilities of both broader range of opportunities for use of knowledge to enhance health and health care than has been achieved to date by traditional CDS methods, as well as to potentially reduce the implementation and usage challenges. These opportunities include use of context awareness, adaptation to cognitive intent and workflow, and dynamic assembly of needed resources. This talk will briefly review the history and state of the art of knowledge-enhanced health IT, and identify a set of research initiatives aimed at reimaging the approaches to this need.

Shumei Kato, M.D.Associate Professor of Medicine, Gastrointestinal and Experimental Therapeutics Program, UCSD Moores Cancer Center.  "Genomics and Immunotherapy Making Matched Targeted Combination Approach a Clinical Reality."

Abstract: Although targeted therapies and immunotherapies can demonstrate salutary anti-cancer effect in portion of patients, unfortunately many tumors show resistance to cognate mono-therapies, and majority of patients who do respond eventually develop resistance. Factors that may limit response to matched targeted mono-therapies include genomic heterogeneity and complexity, as well as the fact that most patients with advanced malignancy often harbor distinct molecular profiles (as in the case with snowflakes). Moreover, understanding molecular findings and accessing drugs/clinical trials can be challenging. To implement a precision medicine strategy, we initiated a multidisciplinary molecular tumor board with a goal of developing N-of-One treatments that could be initiated by the physician under the auspices of a master protocol (UCSD-PREDICT study, NCT02478931). Preliminary results to date show that implementation of tissue next-generation sequencing, cell-free DNA assay, transcriptomic and immunohistochemistry to guide personalized/customized matched targeted therapy approach is feasible and can improve clinical outcomes including progression-free survival and overall survival. Representative patient cases managed with personalized/customized targeted therapy approach will be discussed. 

Bio: Dr. Shumei Kato is Associate Clinical Professor at the Gastrointestinal and Experimental Therapeutics program, UCSD Moores Cancer Center. Dr. Kato’s research interest has been the identification of molecular targets among patients with diverse cancers, as well as to identify the response/resistance mechanism from targeted and/or immunotherapeutic agents, that may be transformed into patient care.
